RU LER.

SPECIFICATION forming part of Letters Patent No. 404,593, dated June 4,1889.

' Application filed January 3, 1889. Serial No. 295,283. (No model.)

To all whom it may concern:

Be it known that we, ARTHUR BROWN and PETER C. FAYETTE, both of Detroit,in the countyof WYayne and State of Michigamhave jointly invented a newand useful Improvement in Rulers, of which the following is aspecification.

Our invention consists in an improvement in rulers, hereinafter fullydescribed and claimed, the object of which is to obviate inking thebooks or the fingers of the user in handling the ruler.

The drawings are all side elevations, Figures 2, 3, and 5 being partlybroken away to show the construction.

A represents a wooden ruler, preferably grooved on both edges, as shownat E F.

Inches and fractions of inches are indicated on one of the groovededges, and the side marked G may be somewhat narrower than the otherside to permit the inch and fractionof-inch marks to be plainly seen andto facilitate the use of the ruler for cutting paper.

B represents a wire secured to the ends of the ruler and set out fromthe edges thereof in line with the center of the groove F, to provide astraight-edge for ruling, and by this construction the ruler A may bepicked up by catching the edges with the thumb and finger withoutbringing the fingers in contact with the outer surface of the Wire B,against which the pen rests when ruling. The wire B may be fastened tothe ruler in a number of ways. As shown in Fig. 1, it is carried beyondthe end of the ruler, bent in U shape,

then bent downward, and its end enters the end of the ruler at the pointmarked E. .In Fig. 2, instead of passing down and entering the end ofthe ruler, the wire is carried back along groove F and enters the .edgeof the ruler at the bottom of the groove at the point marked E. In Fig.4 the wire is simply bent down at the point 0 parallel with the end ofthe ruler and enters the end, as in Fig. 1. In Fig. 5 the wire is bentat the point C, so as to enter the end of the ruler diagonally. In

:Fig. 3 a strip of metal D is'used instead of a wire, and is inserted ina saw-kerf made in the bottom of groove F, and is secured in place byrivets passing through the ruler and the metal strip.

l/Ve usually prefer to carry the metal straight-edge somewhat beyond theends of the ruler, as shown in all the figures except Fig. 4; but thisis mere matter of choice.

It is evident that with a ruler thus constructed ink from the ruling-penis left on the metal straight-edge instead of upon the ruler, and thatthe ruler can be readily picked up by its edges without inking thefingers.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination of a ruler grooved on both its edges and a metalstraightedge secured to the ruler and projecting centrally therefrom,one of the grooved edges of said ruler having inches and fractions ofinches indicated thereon, substantially as described.

2. The combination, with a ruler grooved on both its edges, of a metalstraight-edge set out centrally therefrom and secured to said ruler atits ends only, substantially as described.
